Arginine combination with fluoride and calcium glycerophosphate: effects of concentration and on biofilm fluid.

To study the influence of varying concentrations of arginine (Arg) combined with fluoride (F) and/or calcium glycerophosphate (CaGP) on biofilms. Biofilms were analyzed for acidogenicity, microbial viability and Ca, F and inorganic phosphorus (P) concentrations. For total bacteria, the lowest viability was found in F-containing groups, regardless of the arginine concentrations and presence of CaGP.

Photobiomodulation in the treatment of xerostomia associated with hyposalivation in a pediatric patient with systemic scleroderma.

Scleroderma is a rare autoimmune disease characterized by excessive collagen production. The oral manifestations of the patient with scleroderma can include microstomia, xerostomia, and changes in the resorption teeth. We report the case of a 7-year-old female patient diagnosed with systemic scleroderma where photobiomodulation therapy was used to treat xerostomia associated with hyposalivation.

COVID-19 (SARS-CoV-2) infection and thrombotic conditions: A systematic review and meta-analysis.

Background: COVID-19 is an infectious disease caused by SARS-CoV-2 associated with haematological manifestations (thrombolytic events).

Aims: Considering the high prevalence of the thrombotic scenarios associated with COVID-19, the aim of this study was to perform a systematic review of the available literature, concerning the relation of COVID-19 and the thrombotic events, and identify prognostic factors for these events.

Materials & Methods: PubMed, Web of Science and Scopus databases were searched.

Effect of arginine on microorganisms involved in dental caries: a systematic literature review of studies.

This systematic review aimed to discuss the effects of arginine on caries-related microorganisms in different biofilm models. The eligibility criteria were studies that evaluated the effect of arginine at different concentrations on caries-related microorganisms using biofilm models. Eighteen studies published between 2012 and 2019 were included.
